Answer 1

Answer: 3/5 + 2 3/4
= 3/5 + 11/4
= 12/20 + 55/20
= 67/20
= 3 7/20

Answer 2

Answer:

Answer:

3/5 + 2 3/4 = 3 7/20

Step-by-step explanation:

2 = 8/4

2 3/4 = 2 + 3/4

then:

3/5 + 2 3/4 = 3/5 + 8/4 + 3/4

= 3/5 + (8+3)/4

= 3/5 + 11/4

3/5 = 12/20

11/4 = 55/20

then:

3/5 + 11/4 = 12/20 + 55/20 = 67/20

67/20 = 60/20 + 7/20 = 3 + 7/20

= 3 7/20

Answers

we have that

$((x+4))/(3) / (6)/(x) = (x*(x+4))/(3*6) \n \n = (( x^(2) +4x))/(18)$

therefore

case a)
$((x+4))/(3) * (x)/(6)$
Is equivalent

case b)
$(6)/(x) * ((x+4))/(3)$
Is not equivalent

case c)
$(x)/(6) * ((x+4))/(3)$
Is equivalent

case d)
$((2 x^(2) +4x))/(6)$
Is not equivalent

case e)
$((2 x^(2) +4x))/(18)$
Is equivalent

Hence

the answer is

$((x+4))/(3) * (x)/(6)$

$(x)/(6) * ((x+4))/(3)$

$((2 x^(2) +4x))/(18)$

Answer:

The correct representation of the expression are:

$(x+4)/(3)((x)/(6))$

$((x)/(6))(x+4)/(3)$

$(x^2+4x)/(18)$

Step-by-step explanation:

We are given an algebraic expression as:

$(x+4)/(3)$ ÷ $(6)/(x)$

This expression could also be written as:

$=((x+4)/(3))/((6)/(x))$

We know that any expression of the form:

$((a)/(b))/((c)/(d))$ is given by:

$((a)/(b))/((c)/(d))=(a* d)/(b* c)}$

Hence, we get the given expression as:

$=((x+4)/(3))/((6)/(x))=((x+4)* x)/(3* 6)\n\n=(x+4)/(3)* (x)/(6)$

Also, on solving we get:

$=((x+4)/(3))/((6)/(x))=(x^2+4x)/(18)$

Which graph represents 6x -2y> - 11

Answers

Answer:

Step-by-step explanation:

Remember when using the inequality sign < or > the line will be dotted so we can immediately eliminate answer choices b and d

Now let us solve for y

6x-2y>-11

step 1 subtract each side by 6x

now we have

-2y>-11-6x

step 2 divide each side by -2

-11-/2=11/2

-6/-2=3

IMPORTANT -when you divide inequalities by a negative number you flip the inequality sign

So now we have

$y<3x+(11)/(2)$

See image below for reference

When the inequality is facing x the solutions are going to be on top of the line

hope this helps!

a ski shop has a markup rate of 50% find the selling price of skis that cost the store owner $300. tell me how you got the answer

Answers

if nthe shop has a mark up rate of 50% and they cost 300 to buy you multiply 300 by 50% convert 50% to decimal
so you do .5*300=150
then you add 150 to 300 which means that the shop sells the skis for 450 dollars.
